Smart Hospital Queue System using 8051 & NodeMCU (Code & Circuit Diagram)

Smart Hospital Queue Management System, you already know how this project eliminates long waiting room lines using live IoT tracking.

Below, you will find everything you need to build this yourself, including the complete component list, the circuit diagram, and the full source code for both the 8051 microcontroller and the NodeMCU. Let's build it!

Hardware Components Required

8051 Microcontroller (AT89S52)

NodeMCU ESP8266

LCD Display (16x2)

Push Buttons (for token generation

Connecting Wires & Breadboard

CIRCUIT DIAGRAM

Here is how to connect the 8051 to the NodeMCU to pass the token data to the cloud. Make sure your ground (GND) pins are connected together
